Solution Overview

Problem

Existing cyclocomputers require page-turning operations that disrupt cycling balance and safety due to the need for finger movements perpendicular to the handlebar, necessitating a safer and more ergonomic input mechanism.

Innovation Solution

A cyclocomputer with an adjustment knob mounted on a holder that allows page-turning via a finger while holding the handlebar, featuring ergonomic dimensions and non-slip surfaces for safe and convenient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If page-turning keys are disposed at different positions on the cyclocomputer body, then the user can access different data pages, but the user's hand position must be moved which disrupts cycling balance and safety

Engineering Contradiction:
Improvedata page accessVSAvoidcycling safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines multiple data page access functions into a single adjustment knob located at a fixed position on the cyclocomputer body. This allows users to access different data pages by rotating the same knob in different directions or positions, eliminating the need to move hand position between separate keys and thereby maintaining cycling balance and safety.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If keys are used for page-turning operations, then data pages can be turned, but the finger must apply force in a direction different from the holding direction which disrupts cycling balance

Engineering Contradiction:
Improvepage-turning operationVSAvoidcycling balance
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent inverts the traditional key-pressing operation by using a rotation-based adjustment knob. Instead of pressing keys perpendicular to the handlebar holding direction, users rotate the knob along the handlebar axis, allowing the finger to apply force in the same direction as the holding direction, thereby maintaining cycling balance.

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of operation

If the adjustment knob is positioned too far from the handlebar, then it is easier to operate the knob, but the user's finger cannot reach it while holding the handlebar

Engineering Contradiction:
Improveknob operationVSAvoidfinger reach distance
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

The patent optimizes the distance parameter between the adjustment knob and the handlebar to a specific range that balances operability and reachability. This parameter optimization ensures the knob is positioned far enough to be easily operated but close enough to be accessible to the user's finger while maintaining the handlebar grip.

Inventive Principle:
Principle #35Parameter changes

4Length of moving object

If the adjustment knob is positioned too close to the handlebar, then the user can easily reach it, but it becomes difficult to operate the knob without moving the hand position

Engineering Contradiction:
Improvefinger reach distanceVSAvoidknob operation
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The patent optimizes the distance parameter between the adjustment knob and the handlebar to a specific range that balances operability and reachability. This parameter optimization ensures the knob is positioned far enough to be easily operated but close enough to be accessible to the user's finger while maintaining the handlebar grip.

Inventive Principle:
Principle #35Parameter changes
